All the main antagonists from JoJo's Bizarre Adventure's installments 2-7(Battle Tendency, Stardust Crusaders, Diamond is Unbreakable, Golden Wind, Stone Ocean, and Steel Ball Run) have all been staying in the residence of Yoshikage Kira from DIU; forever surrounded by one another in a never ending sleepover!!! :)
The antagonists of JoJo's Bizarre Adventure had all agreed(besides Kira) to have a sleepover in Yoshikage Kira's humble mansion in Japan.

Everyone resides in Kira's residence in Morioh, Japan. Kars is in the attic, Kira in the kitchen, Diavolo in the closet with Doppio beside him, Pucci and Funny Valentine on the couch, and Dio in his room downstairs having a rather vulgar conversation with one of his many women.
